The escape of molecules from the surface of a liquid is known as .

Further Explanation:

Phase transition is defined as the change from one state to another state but no change in chemical composition is observed. It is also known as a phase change, state change or physical change.

Sublimation

It is the process by which a substance directly gets converted from solid to vapor phase, without going through the liquid state. Naphthalene and dry ice are substances that undergo sublimation.

Condensation

It is the phase transition that occurs when vapors are converted into liquid. This is done by changing the temperature and pressure of the substance.

Evaporation

In this process, liquid changes into vapors. Here, temperature has to be elevated or heating is done. Energy is used up in the substance and therefore it is an endothermic process.

Boiling

It is a phase change in which liquid is converted to a gaseous state when liquid is heated to its boiling point.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
